To aZZ whom it may concern:

Be it known that T, GEORGE A. Donna, the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Water-Coolers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to improvements in water-coolers for internal combustion engines. It relates more particularly, however to improvements in radiators of the portable type or those mounted upon tractors, trucks and other forms of gas propelled vehicles. Y

The main object of the invention is to construct a radiator so that the water to be cooled will flow through a series of spaced receptacles, one above another, having bottoms composed of foraminous material, and that in the passage from one to another the water will descend through the air in a finely divided form so as to be very rapidly cooled.

Another object of the invention is to construct a radiator wherein the water will be so rapidly cooled that the loss thereof due to vaporization will be reduced to aminimum.

Still another object is to provide a type of radiator that will be simple in construction, that can be produced at a comparatively low cost, and that can be readily repaired by an inexperienced person in but a short time at small expense.

Still another object is the provision of a the parts can be mainl produced from dies and readily and quic rly assembled.

Qther objects and advantages will appear as the description of the invention proceeds, aided by the accompanying drawing where- 111:

. to produce them. Further than this the radlators, particularly those used on tractors, do not cool the water quickly enough to prevent rapid vaporization often causing considerable inconvenience.

My radiator is designed to keep the water properly cooled under the most exacting conditions.

1 indicates a tank large enough to contain the amount of water to be used in the radiator. Secured to each of its ends is a pair of upstanding angle bars 2 held a hood spaced above said tank comprising end portions 3, for example, bolted to said angle bars, and the sides and top portion a and 5 respectively, while 2 indicates a pair of bars secured to the top of the said tank 1 for supporting the whole structure upon the vehicle with which it is used.

Stationed between the tank 1 and said hood is,,a series of hopper-like trays 6 whose walls are preferably straight forming rectangular trays spaced from one another, the lower portion of one depending well down into the other as clearly shown in Fig. 1, the areas of their lower portions being less than their upper portions.

Each is provided with a bottom of foraminous material 7 such as wire screen or perforated metal, or other suitable material, which may be attached thereto but preterably in such a way as to be easily removed.

The lowermost tray of the series may or may not be provided withthe screen but in any event it is secured to the top of the tank 1 in a water-tight manner, the latter having an opening 8 in its otherwise closed top for receiving all of the water from the said series of members, and any means may be employed to prevent the water from slopping over the sides of the" sald lowermost member if, indeed, it is found necessary.

9 indicates an outlet in "the side of the tank for the water. 9 is indicative of any suitable pumping means ijior elevating the water from said tank and discharging it inside the hood through a pipe 10. The water thus introduced is preferably sprayed throughout the hood so as to break it up its descent through the several trays 6.

Two methods of accomplishing this spraying are shown herein although there are other ways open for use not necessary to describe. f

In Figs. 2 and 4:, for example, isshown a between which is or main purpose is ing the water.

which in this instance serves two purposes. Its use in connection with the spraying will first be described. It stands opposite the discharge end of the pipe 10 and is indented at 12 as shown. The water is forced upon or into such indentation and is caused to be thrown violently in all directions upon the walls of the hood thence descending by gravity through the several trays 6 and their bottoms 7.

In Fig. 5 another method is shown. The discharge pipe in this case is denoted by 13 and enters the top of the hood. Beneath its discharge opening is a deflector 13 of any desired form, suitably supported, upon which the flow of water is discharged to obtain the required or desired spraying action.

The stand-pipe 11 in the first described form of the apparatus is employed for spraying purposes only as a convenience and in the absence of a special deflector. Its real that of assisting in cool- As shown in Figs. 1 and 2 it extends from close to tlie'top of the tank 1 up to, and opens out through the top of the hood. The lower end is provided witha small opening 14, Fig. 4, and at intervals throughout its length is furnish-ed with slits 15 between the bottoms of the trays 6.

16 indicates an exhaust pipe from the engine, not shown, which pipe enters thestandpipe 11 and turns upwardly into a nozzle within the same.

In action, the water as sprayed within the hood 3, 4, 5 falls upon the foraminous bottom of the uppermost tray 6 and in its passage therethrough is finely divided, passing successively through the other bottoms of the members 6 lower down until it finally enters the tank or receptacle 1 from which it is returned to the hood by the pump keepingI up a continuous flow.

he water in its finely stand-pipe 11 divided form in its descent is exposed to the air which has free access to the interior between the trays 6, and the entrance of the air thereto is aided by the forced air currents in the stand-pipe.

That isto say, the exhaust from the upturned end of the pipe 16 acts on the injector principle and creates a strong upward air current in the said stand-pipe drawing in air through the slits 15. This, of course draws air'inwardly between the trays 6 which in meeting the descending water in its broken up form, as it passes from top to bottom of the radiator, acts to rapidly cool it.

Through the opening 14 of the stand pipe 11 the draft withdraws more or less of the va ors and heat from the tank 1.

he walls of the hood 3, 4, 5 prevent loss of the water being sprayed and in order to prevent splashing of water over the sides of the uppermost tray 6, in striking the bottom 7, a hinged lid 17 is provided at each side of the hood to cover the opening at each side within adjacent trays,

as most clearly shown in Fig. 5. These lids are erforated so that air may enter and circu ate beneath the hood to assist in cooling.

The form of arrangement shown in Fig. 5 last referred to does not showthe stand-pipe 11 which pipe need not be used though preferable as aiding faster reduction of heat.

It is now to be noted that by providing a series of spaced diaphragms such as 7 of foraminous material the water in its fall is form that all of it is exposed to the air in that form time and again, besides which, the material of which the several trays 6 and their bottoms 7 may be made will rapidly radiate the heat, by being separated from one another, and quickly remove the heat from the water that falls upon them.

The cooling action is particularly rapid, of course, when the radiator is carried upona tractor, truck, pleasure car, or other moving body because of the forced movement of the air therethrough. f

I am aware that an exhaust pipe has been erected within a radiator for assisting in cooling the water but it has not been applied in the manner herein shown and described.

Further, I am aware that a pumping device is not new in a radiator except in combination with the structure herein.

Since the radiator is of open form throughout, any part mayi be readily reached for insertion or removal of bolts or the like, and any other part may be removed or replaced without disturbing others. The spacing of the trays 6 may be such that any one of them may be readily extracted by removing the bolts that secure it to the angle bars 2, all of which will be understood.

I may make such changes in the construction of my apparatus as may be considered within the invention and the scope of the accompanying claims.

My construction is such as to be peculiarly fitted as a portable radiator or one for use upon motor v hicles, especially tractors, the trays 6 being dropped into one another far enough to prevent loss of water either by splashing or slopping as the vehicle rocks and rolls.

Though not shown, the pipe 16 may be covered with asbestos or other suitable material, or may be otherwise protected so that it will not heat the air in the hood nor tend to heat the water falling toward or around it.
